ADAM COOK, OF PITTSBURG, PENNSYLVANIA.

IMPROVEMENT IN WASHING-MACHINES.

Specification forming part of Letters Patent No. 157,195, dated November24,1874; application led September 12, 1874.

To all lwhom it may concern Be it known that I, ADAM COOK, of Pittsburg,in the county of Allegheny and State of Pennsylvania, have invented anew and Improved Washing-Machine, of which the following is aspecification:

In the accompanying drawing, Figure 1 represents a sectional sideelevation of my improved washing machine, with wash board thrown up;Fig. 2, a vertical central section of the same with wash-board inposition on the clothes, and Fig. 3 is a detail bottoinview of thecorrugated wash-board.

Similar letters of reference indicate corresponding parts.

The invention will first be fully described, and then pointed out in theclaims.

In the drawing, A represents the wash-tub, which is placed on a verticalcentral shaft, B, passing through the strong diagonal bracepieces B',applied firmly to the upright supporting-standards O, with connectingdetachable rounds C. The rounds O are applied only at opposite sides tothe standards, so that Athe attendant may readily operate the machine atthe intermediate sides, with no rounds to hinder the legs or feet. Aslotted quadrantal piece, D, connects at suitable height two adjoiningstandards O. A clampscrew, a., of one standard, running along itsslotted part, Aserves to bind ijrmly the standards and rounds togetherafter the latter have been inserted. The tub-supporting frame can inthis manner be made cheaper, and is more readily shipped and set up;

VVash-tub A is provided at its upper circumference with a solid ring orfly-wheel, E, which is supported on strong bands or brackets b of thetub, to be readily used as a hand-wheel for revolving the tub orswinging the same alternately from right to left, as found mostconvenient. The bottoni of the tub is conf structed with paralleleorrugations, and with a stationary upright standard, F, of wood orsuitable metal, for the purpose of guiding the wash-board G thereon whenit is placed in position on the clothes. The under side of thewash-board has similar parallel corrugations or grooves as the bottom ofthe tub, which are more advantageous than the radial grooves commonly inuse, as the clothes are only taken hold of and rubbed when thecorrugations are crossing each other, but slide lengthwise in the samewhen they are parallel to each other, so that the tub may be morequickly and readily started by the operator without requiring the extrapower necessary to overcome the continual drag or pull of the clothes inradial grooves. rlhe wash-board G slides by its upright guide-standardsG in perforations of the diagonal cross-bar H, and is held by a suitablespring-catch, d, Aof the same in raised position, so that the clothesmay be readily placed in the tub or wrung out. The crossbar H is pivotedto diagonally-opposite standards O, being provided at one side with asetscrew, e, for being tightened thereto, and at the other side with aslotted segmental guideplate, f, and clamp-screw f', for being swungover with the wash-board, and secured in a position entirely out of theway for the manipulation of the clothes.

When the clothes are put in the tub with the water and suds, theclamping device is released, and the wash-board swung back and loweredthereon. The tub is then rotated or reciprocated by the ily-wheel untilthe clothes are cleaned, then taken out and passed through the wringer,which is attached to its supporting-piece, and therefore not liable toinjure the tub. The whole machine forms thus a very strong, durable, andconvenientlyoperated washin g apparatus.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. The wash tub supporting frame, coinposed ofdiagonal braces Bf, upright standards O, detachable side rounds O', andsegmental wringer-piece D, applied as described, for binding the partsrigidly together, as specied.

2. The wash-tub having attached at its upper circumference a ily orhandle wheel for operating the tub, as set forth.
